Filter by:The investigators will study the use of a home-based spirometer (Spirobank Smart spirometer) that connects to a smartphone app (VitalFlo) in teenagers with persistent asthma to determine if clinically significant changes in lung function detected by the spirometer are associated with patient-reported asthma symptoms.
Study of the palatability and acceptability of dexamethasone oral tablets crushed and placed in apple sauce or pudding in comparison with the IV solution mixed with sugar syrup and given orally. It is hypothesized that dexamethasone tablets crushed and administered in apple sauce or pudding will be more palatable and acceptable for pediatric patients receiving dexamethasone for an acute asthma exacerbation or croup.
This randomized study compares operative techniques in chronic rhinosinusitis with polyposis (CRSwNP) surgery. It aims to evaluate outcomes in asthma and CRSwNP, safety and costs. The investigators want to see if patients with certain clinical and/or genetic predispositions will benefit from extended surgery. They also aim to find biomarkers for detection and management models for of severe airway inflammation and to further develop markers for progressive disease forms.
A trial to investigate if a single dose of the oral corticosteroid, Dexamethasone is as effective in treating exacerbations of asthma in children as 3 days of treatment with another oral corticosteroid, Prednisolone
In asthma, the type and importance of the inflammatory response in the airways has allows identification of different phenotypes. Of these, one of the most common is eosinophilic asthma, based on induced sputum differential cell count. Patients with severe asthma and an eosinophilic asthma phenotype have different pathophysiological characteristics than those seen in patients with with mild asthma. However, few studies have compared patients with eosinophilic phenotype according to the severity of asthma. In addition, the stability of the phenotype based on the sputum results has been criticized. This study aims to describe the characteristics of patients with eosinophilic asthma phenotype according to the severity of asthma and determine the stability of the phenotype.
The Pulmonary Specialist-Health Coach Consultation (PuSHCon) study examines the implementation of health coach-assisted consultations to improve access to specialist care and implementation of specialist recommendations for patients with COPD, asthma, and asthma COPD overlap syndrome (ACOS) for low-income and vulnerable patients seen at public health clinics. Three hundred sixty (360) patients from ten clinics will be enrolled in the study and randomized at the individual level to receive health coaching or usual care; 180 patients will receive usual care and 180 patients will receive the PuSHCon model.
Asthma is often associated with various comorbidities that may influence its clinical expression. Among those, chronic rhinosinusitis with nasal polyposis (CRSwNP) is observed in 5% of cases. Asthmatic patients with CRSwNP appear to have more severe and poorly controlled asthma, as well as greater bronchial and systemic inflammation, especially those using inhaled corticosteroids as control medication. However, this remains to be validated. In the last decade, there has been interest labeled for phenotyping of asthma and CRSwNP. However, there is scarce data on the phenotype of asthma with CRSwNP. This study aims to describe the phenotype of asthmatic patients with CRSwNP according to the clinical, physiological and inflammatory characteristics and whether there is a more severe phenotype related to the dose of inhaled corticosteroids and the percentage of induced sputum eosinophils.
The Goal of this study is to investigate if individuals ages 12 years and older, carrying the IL-4RαR576 gene variant, will have a greater response to therapy acting directly on the anti-IL-4R. This will be conducted by examining the effect of a 48 week therapy with dupilumab on the rate of asthma exacerbations.
Exercise intolerance is one of the most problems in chronic obstructive pulmonary disease (COPD) and occurs not only in performing lower body tasks but also in performing arm activities. During arm exercise, auxiliary respiratory muscles are used for arm duty and cannot contribute to breathing. This increases the respiratory load of the diaphragm, which is mechanically disadvantageous, and results in thoracoabdominal synchronization disorder and severe dyspnea. Although the relationship between activity limitation and quality of life is clear in patients with exertional activity, the literature on physical activity is insufficient. Exercise and physical activity can also and exercise-related respiratory symptoms are known to have adverse effects on daily living activities (ADLs). There is no gold standard for objective assessment of activity limitation and exertional dyspnea in patients with asthma. Therefore, the results obtained by evaluating the validity and reliability of the 6PRT test in asthmatic patients in this study will increase the use of this test to test both arm endurance and arm exercise capacity in adult asthmatic patients, to estimate the effect on ADLs and to demonstrate the development obtained with pulmonary rehabilitation. .
This study is a cross-sectional, non-interventional study based on existing data (NISed).
